Improvement in sowing-machines



UNITED STATES ATENT rtree.

P. SEYMOUR, OF EAST BLOOMFIELD, NEW YORK.

Specification forming part'of Leiters Patent No. 41,036, dated May 7, 1545.

.ing a part ot' this specification, in which- Figure l is a tcp View of said machine. Fig. 2 is a bottom view ot' the seed-box. Fig. 3 is a side elevation ot` Fig. l, and Fig. 4 is an inside view of one end of the seedbox.

A B, Fig. l, are the wheels that support the machine. 4

V V are the shafts that guide the machine when drawn by a horse; C, the axle-tree; D

D, the frame-work that supports the chair El and rests on the axle-tree and seed-box, and is secured to the axle-tree by bolts or dowels.

On the wheel B is a cylinder, a, secured to the spokes of said wheel by keys or pins. In said cylinder is an angular groove, which works `the bar I to and fro.

Gris aplank secured to the axle-tree and seedbox and supports the bar l. This bar is a lever with a pin in one end that tits the angular groove in thecylinder e. Near the middle o'f this lever is a pin on which the lever moves. At the other end is a strap of iron connected to said lever by a pin, so as to form a joint. This strap of iron is secured to the rod H ato by a pin.

H is a rod vin the top ot' the seed-box F F, and is operated by the lever I.

It 7L is a side view ot' H. Thisis arod or bar ot' wood having flat pieces of iron secured to it, which go down into the machine nearly to the bottom, and is called the stirring-bar77 or plaster-breaker,77 and is used in sowing damp or wet plaster.

Secured to the wheel A is a cylinder, b,with

a zigzag groove.

K is a plank-work fastened to the shaft V, and supports the lever e.

e is a lever with a pin iii one end that tits the zigzag groove in the cylinder b.

plankwork and lever are several holes, in either of which a pin may be put, which serves as a fnlcrum to this lever, making it a lever with a 'movable fulcrum, so that a long or short mo- -an oblique motion.

Through the tion may be given to the lower end ot" the said lever e.

v m x, Fig. 2, is the lower edge ot' the back side of the seed-box, and is faced with iron.

c o is a square rod, faced with iron wider than therod, and so placed on a n, which is the lower edge of the forward side ofthe seed-box, as to close the aperture in the bottom ct' said box with the iron plate ot'the rod c c. This rod is then pressed closely to the bottom ot' the boX F F and kept there by the iron guards or stirrups s s.

r fr r are plates ot' iron with a hole in each end of each plate, and one end of each plate is connected with the rod c c by a pin, so as to form a joint. These plates are then placed on an angle of forty-five degrees, or any angle at pleasure-,but all on the same angle. The other end of each plate is then connected to T T, which is a strip of wood xed to the under side ofthe box F F for that purpose. This rod c c l call the gage-rod 7 or a parallel oblique slide, because the iron plate on this rod is parallel to theiron plate e and remains parallel thereto while its motion in opening or closing the aperture in the bottom of the seed-box is By forcing this slide endwise one way it enlarges the aperture in the bottom of the machine, and by forcing it the other way it diminishes it. This may be done by a screw or lever or rap of'a hammer, or otherwise. By this oblique rnotionof the slide the machine may be set close enough to sow grass-seed or open enough to sow peas.

`y is an index or pointer, one end of which is made fast to this slide by a pin, so as to form a joint. Near the same end another pin passes through this index into the seed-box, so as to form another joint so that the motion of the rod c o moves the index. With the help ot' this index the machine may be set to sow anygiven quantity per acre.

m and m m and -m m m, Fig. l, are three differentrods, called vibrating rods 7 or dropping-rods.77 They areforsowingdiierent kinds of seed or material. One only is used at a time. m mfin Fig. 2 is represented in Fig. l by a side view, being one of the three. m has a plate of iron, which is hacked, so that it is a kind of coarse saw. Thisis used for sowing plaster, ashes, and lime. m mm has a plate of iron with notches, and is used for sowing e, Fig. 2, is lower end ot' the lever e, Fig. 1,'

and is connected with the rod 'm 'm by an iron hook, which hooks into the lever e at W and to the rod m m at P. By taking out this hook and raising the slide-door R the vibrating or dropping rods may be changed at pleasure. These rods rest (one at a time) on the guards or stirrups s s, and are made to vibrate by the lever e, which is operated by the zigzag cylinder b. N, Fig. 3, is an upright post with a pulley in the top.

To the upper end of the lever e is attached a cord, which passes over the pulley in the post N to theehair E. By pulling this cord the pin in the upper end of the lever e is thrown out of the zigzag groovein the cylinder b, and thus the machine is made to stop sowing at pleasure.

What I `claim as my invention, and desire to secure by Letters Patent, is-

The manner in which 1 have combined the stirring rod or bar H with the dropping-bar or vibrating rod m m, and in combination there with the gage-rod c c, with its index for regulating the amount of seed to be dropped, in the manner above described.

PLE RPONT SEYMOUR.
